Silent Hill 1, could be updated to the Silent Hill 3 engine. I would love to see that. SH1 still has great atmosphere even with PSone graphics, would be great if it was updated. Maybe all silent hill games from 1 to 3 could use a remake, using modern graphics and all that. The gameplay must stay clunky, camera still has to be a problem, I like when they only remake the graphics and make the UI more friendly, not when they try to modernize the gameplay. What makes that game scarry is the fact you hear things, but don't see them. The more you see, the more control you have, worse the game gets, see all the other Silent Hill games (Homecoming, Downpour, Origins), they show this clear as water.
C&C: Tiberian Sun as well, with 2d graphics but high quality you know, maybe add the 3rd faction that was cut out, plus some more cut content as well.
And I agree with you OP, Battlefield 1942 remake would be great.
